the above described character, other objects will appear to those skilled in the art to which it appertains from a consideration of the following detailed description of the different embodiments of the invention taken in connection with the accompanying drawings, in which Fig. V1 is a plan partly in section of a toilet seat and hinge posts with one form of stop means incorporated therewith;

Fig. 2 is a perspective view of one of the hinge posts and cooperative sleeve of Fig. l;

Fig. 3 is a sectional view taken on the line 8 3 of Fig.` 1, and

Fig. 4 is a perspective view similar to 2 of a modified form of the invention.

Referring to the drawings in detail'the reference character 9 indicates a toilet bowl which is usually constructed of porcelain and is provided with a pair of vertical apertures 10. A pair of hinge posts 11 and 12 having threaded Shanks 13 may be positioned in the apertures 10 in the toilet bowl and may be secured in position by wing nuts 14.

A toilet seat 15 has a rearwardly extending projection 16 which is positioned between the two hinge posts 11 and 12 and is pivotally connected th-ereto in a manner to be presently described. The seat may comprise a plurality of laminations 17 which are held together by being molded with thin intervening layers 18 of hard rubber or similar material, a somewhat thicker layer or veneer 19 of rubber providing the outer finished surface of the seat. Extending from one lateral edge of the rearwardly extending portion 16 of the seat to theother7 there may be embedded therein a cylindri-V cal sleeve 20. This is shownA as having a plurality of longitudinally extending grooves or corrugations 21. When the laminations ofV whichy the seat is made are placed Vto-I gether the sleeve 20 is molded in place, asV it .were, by virtue of the rubber or other plastic material being forced into the corrugatioiis 21 and after lthe plastiomaterial has hardened the sleeve is thereby firmly secured in' place. At each end the sleeve 2O may have substantially one-half thereof extend fai@4 ther longitudinally so asfto 'provide a stop V22.

The upper portion of each hinge postmayf v be provided with a horizontallyextending cylindrical pin 23 which is preferably integral therewitli. l An annular portion 24V may extendoutwardly from each. post around thel pin 23. `A segmental portionv or projection 25 may extend somewhat farther from the Ihinge post than the annular portion 24 and,

has a surface 26 against which the stop k22 on the sleeve -20 comes torest.-` It may be noted that the annular portion 24' is some.

what smaller in diameter than the opening in which the sleeve 2O is placed so that there isa clearance between the-portion24 and` the seat 15 as indicated atr 27. 4This pre` vents any contact or rubbing at this point and particularly eliminates any possibility of the external veneer of rubber 19 from being chippedV at the edges of the opening Furthermore it will be noticed that the annular portion 24 prevents dirt from readilyl reaching the bearing proper which is .bei-

tween' the 'pin-4 23 'and the sleeve 2O,` The foregoing construction results in both the stop and bearing beingwell recessed within the seat so that they are not visible and the assembled arrangement has a neat and compact appearance. Y l l In assembling the parts .ona water closet 'bowl the bearing .pins 28 of the hinge posts' 11 and 12 are firstv inserted into the seat and into the inner portion of the sleeve 20. The threaded Shanks 13 of the posts are then placed in the apertures 10 of the bowl 9 andV secured in position by means of the wing nuts uiol ' so l cured therein or integral therewith. The sleeve 20a is provided with a stop 22a which 14:. In describing the operation of the ooncealed check hinge, attention is first called to the relative position of the parts as shown in 'Fig. 1, 'the perspective view of Fig. 2 being right position Vindependently of any wall Y stop or other means external to the hinge itself. y Y

VTwo similar check devices are shown'in Fig. l one at each sideof the rearwardly extending portion 16 ofthe seat but it is obp vious that such checkl means may be provided for one side only. Such a construction is particularly desirable for use in connection with a'removable toilet seat such as described in my co-pending application Serial No. 3111,- 649 filed Feb. 2l, 1929. Fig. 3 shows a'forin one of said pin and socket connections having concealed means for limiting the rotative movement between said seat and posts.

2. In a water closet, a bowl, a toilet seat having sockets in the lateral edges'thereof, a pair of hinge posts positioned at the'sides of said seat near the` rear thereof and secured to said bowl and having pins extending therefrom toward said seat and into said'sockets,

an annular portion for one of said pins positioned adjacent the hinge post, a projection on said portion, and astopadjacent the socket for cooperation with said projection to limit the rotative movement between said seat and said post.

so i In testimony whereof I affix my signature.

l of hingeV stop adapted for use where the -opposite hingeY Apost is of a detachable type. A sleeve 20a which is adapted to be embedded in a toilet seat has a cylindrical pin 28 sepreferably. extends away from the sleeve 20a to distance only su'ioient to provide a rugged construction. The upper portion of a hinge post lla is provided with a socket 29 into which the,v pin 28'may extend to provide a .pivotal connection between the hinge post and the seat. A projection a extends from the post 1l and has asurfacer26a which cooperates with the stop 22a. r It' will be noted that the end 30 of the pin 28 is spherical, in I form and may be'undercut as at 3l. rI`he foregoing arrangement` of the pin and sockete provides for the necessary relative movement therebetween when the opposite hinge is disconnected and the seat is swung away from the opposite hinge post andl at thesame time the pin l28 is swung at an angle to thev socket vr29 andv ready for withdrawal therefrom. To`

obviatepossible confusion on the part'of the reader attention is called to the fact that the construction. shown iii Fig. 3 is adapted for a seatwhich swings inthe opposite direction from that for which the hinge shown in Fig. 2 is adapted; or in other Words itis the construction of a ri @ht hand hiiigelpostinstead Vof aV left hand hinge post. i'
